Stat Quo recently detailed his experiences working on Detox with Dr. Dre. In an exclusive conversation with HipHopDX, the former Shady/Aftermath artist says that he became frustrated with making songs that would never be released.

“I just felt like Detox was just not going to come out,” Stat Quo says. “I was writing so much music and doing so much shit and my frustration with it not coming out began to effect me and Dre’s relationship. I became frustrated to the point where I had become bitter about working.”

Stat Quo says that Interscope CEO Jimmy Iovine considered Dr. Dre’s Detox team “The greatest practice team of all time.”
